From the manufacturer:
Buffered, manufactured acid-free in a neutral environment, it offers excellent protection against ageing. Pulp-dyed, colours are light-resistant and its high cotton content makes it both robust and flexible.
With its two surfaces, Mi-Teintes® has nothing but good sides! One side has a honeycomb grain, contributing to its personality, that easily retains the pigments. The other side has a fine grain, ideal for pencil and charcoal.
Mi-Teintes® meets all your requirements and is also suitable for art and craft.
